Abstract: 13,891. MÚray-Horvßth, C. June 5. Monotype a n d l i k e machines.-Relates to machines for casting single types in order of composition and setting them up. The matrices D in the form of discs are carried by a series of arms E pivoted on a shaft E<b> in a reciprocating slide F. The arms E are held in normal position, as shown, by spring catches k, and when one of these catches is released by a hammer K<o>, the arm swings out and, as the slide F moves, its matrix disc is caught and held upon a projecting stud C<b> on a slide C<a>. This slide carries the matrix up to the end of the mould cavity A, and after the cast returns to normal position. In the return movement of the slide F the projected arm E takes the matrix from the stud C<b> and the arm is moved back by a projection E<a> thereon engaging a fixed cam bar. Means are provided for holding the matrix discs in the arms and for releasing them as they engage the stud C<b>. There are three matrix characters on each disc D, and the stud C<b> is mounted to rotate in its support to bring either the upper or lower character into casting position. The stud is turned by means of two rods, either of which may be projected, by an electromagnet, so that its end comes into position to engage an arm or projection on the stud as it moves towards the mould. The metal is pumped into the mould from the metal pot Z. One side of the mould is formed by a sliding bar or plunger which is released before each cast, so that it may be moved inwards by a spring to contract the mould cavity. Its inward movement is limited by a pin on the plunger slide, which enters a recess in the matrix disc, the depth of the recesses being such that the width of the mould will correspond to the size of the letter being cast. The plunger is held rigidly during the cast by a disc having a number of pins of different lengths, the disc being rotated until one of the pins engages an arm on the slide and prevents its outward movement. The side of the mould opposite the plunger is formed by the edges of a disc, which after the cast makes a half rotation to bring a recess in the disc into position to receive the cast type which is pushed into it by the plunger. When the disc returns to position the type is pushed out of the recess into the receiver. The type is trimmed by a knife on the disc, and by a fixed knife past which the type is moved as it is carried by the disc to the receiver. The hammer K<o> is operated at the required time to release the proper matrix arm E, by an arrangement of levers K<c> the lower ends of which rest on the periphery of a rotating disc K. The periphery of the disc K is divided into two parts by a rib K<a>, in which is an opening through which any of the levers K<c> may be pushed laterally on to the other part of the disc. On each side of the rib K<a> are peripheral recesses into which the ends of the levers may drop as the disc rotates. When all the levers drop simultaneously the hammer is operated, the moment at which this occurs varying according to which of the levers K<c> are pushed over to the other side of the rib K<a>. The levers K<c> are operated by levers H<f> operated by armatures of electromagnets H<g>. When a lever H<f> is operated by its magnet it comes into position to engage a cam-groove in a disc H<i>, by which its movement is completed. The magnets H<g>, and those for operating the rods by which the matrix discs are rotated, are in circuits controlled by a perforated strip passing between a feed-roller L and contact-fingers L<i>. Included in the system of circuits is a current distributer consisting of a disc M having pairs of segments over which revolves an arm M<2> on the shaft N, having a double brush by which each circuit is closed. The disc K is mounted on the shaft N, which is driven by gearing from the cam shaft r driven by the pulley R. The slide F is moved by a pin on a wheel G<d> journalled on an arm G<a> of the shaft N and gearing with a fixed toothed gearing G of twice its diameter. On the shaft r are cams S, T, U, V for operating various parts of the machine.
